        <p>
            MegaMenu component uses the <i>menubar</i> role along with <i>aria-orientation</i> and the value to describe the component can either be provided with <i>aria-labelledby</i> or <i>aria-label</i> props. Each list item has a
            <i>menuitem</i> role with <i>aria-label</i> referring to the label of the item and <i>aria-disabled</i> defined if the item is disabled. A submenu within a MegaMenu uses the <i>menu</i> role with an <i>aria-labelledby</i> defined as the
            id of the submenu root menuitem label. In addition, root menuitems that open a submenu have <i>aria-haspopup</i> and <i>aria-expanded</i> to define the relation between the item and the submenu.
